TO ALL WHOM IT- MAY I v Be it known that I, Gs'onca L. wen; or-nmrora,in the county at Hartford, in the State of Connece ticut, have inventeda new and nseful Improvement in Anti-Friction Journal-Boxes; and I dodeclare that the following-is a full and exact description thereof,reference being h'ad' to thenaccompanying drawings, and to vtheletters'of referendefmarked thereon. v p

Thenatnre'oi my invention consists in providing in journal-boxes a frameor casing for the reception of a number .of round belle, of-fdifl'ere'nt sizes, and thearrangement of them in such manner-as todiminish the friction very greatly it not altogether. v

To. enable 'others. skilled in mechanics Ito-make and nae my invention,I will proceed to describe "58 com struction'and operation. l

Figure Lisa section; on line 1 and 2. Figure 2 is aplan. V Thesameletters of reference are alike in both figures. I

A is" the frame. or casing, that receives the heads orends C D "B is theshaft. la a a" a! are round balls, made of any suitable material, andare placed in an annular recess in the heads (TD, and in the-ends of theenlarged part, of the shaft Br I l l I 'he balls referred'to aresuflicient in number to occupy the whole of the annular time allow theballs to rotate, as the journal to which they may be attached rotates. IIlhrill'be seen that in fig. 2 the balls are shown in dotted lines, andare of two sizes, one a little smaller recess, and ntthe same than theother,'n,nd placed alternately, The ohjectiof making them of two sizesis to insnrea rotary motion .o the balls asthe shaft rotates which wonldnotbe the'easo if all the halls were of the same size, as in that ms ofthem would retard-the next, and so on around the entire circle.ification, the nature of the rBy referenseto the accompanying drawings,which ore-made parrot this spec invention and'the'opero'tion will heclearly seen".

.' It 'iri'll be at once seen that ivhether the shaft he an upright or ahorizontal shaft, the operation is the same,-

thejballs receiving the weight andthrust of the shaft; and by heingeveryother one smallerand larger; half oif th'eh iills only come'in contactwith the bends and enlarged part-of the shaft B with any pressnre, couseqnently the'la'rger balls all rota'tein one directionland'the smallerintermediate ones roll against thela'rge ones, nd keep them apart intheir, proper places, and.arefree'twturnflin the opposite direction, andnot rnb against hut roll'npon the large without frictiomfl p a v p Iprecise formv licre iehowm as theform may be varied, and still I do notproposeto confine myself to the preserve all the characteristics'of myinvention; 1

What I claim as my invention} and. desire to secure by IiettfersjPatent, is-- The combination of the journal-box, having annular.grooves-lathe heads 0 and D and corresponding grooves on both endsof theshaft-hearings, B,'\rith halls of two-difleientsize's, placedalternately in the annulargroovesg-th'e n'hol'e arranged andoperating'ai indfor the piirpose set forth. v H
